> I wasn't aware of that, that's good to hear. I'm under the impression, though, that since SPDY encrypts everything, that you can't get caching at intermediate nodes unless you explicitly MITM yourself, which would reduce the utility of that feature.
Last I heard, it was quite a matter of debate in the IETF workgroup on HTTP2 the extent to which SPDY's "TLS is mandatory" approach would be adopted for HTTP/2.0 (IIRC, Microsoft at one point staked out a "we will enable HTTP/2.0 without TLS in our browser so the standard better allow it" position, and numerous parties making strong arguments that there were definite use cases -- especially internal networks -- where users would want the other advantages of HTTP/2.0 and where TLS would be a burden rather than a benefit.)
And if you are worried about caching internal to your own organization, you could, in the worst case, use a (TLS-required) HTTP/2.0 user facing server with HTTP/1.1 (non-TLS) internal servers, eliminating the need to MITM your own TLS traffic. Obviously, that doesn't help external cacheability, but you probably aren't going to usually want to send external content insecurely from an app.
